Proved natural gas reserves in Saudi Arabia are over 7 trillion cubic metres (250 trillion cubic feet). Global production in 2009 reached 29 billion barrels (4.6×10^9 m3) of oil and 3 trillion cubic metres (110 trillion cubic feet) of natural gas.The country has had plans to diversify its energy sources for some time, developing solar and nuclear power.
